Procedure Subprogram Help 2

[SucreTeen123]

Anyways I am horrible at Turing and I really need some help! So whoever is out there help!!!!!!!

Question: Write and test a procedure subprogram called swap for swapping the values between two string variables given as parameters of the procedure.


Thank you!

first off, you'll need something like this:

Turing:

proc swap (var a, b : string) end swap

Now what you've done is created parameters that will change the variable you used. for instance:

Turing:

proc add_5 (var x : int)      x += 5 end add_5 var num : int add_5 (num)

Now if you put num, it will be five. If you define your parameter as a variable, it makes it mutible, so it will change it on the outside. Without var, it turns them into constants within that procedure.

So now that you know this, you have a simple task. Find a way to assign a and b's values to eachother
